Alpine DP2-35M Review: A 3.5-Inch DP2 Midrange for Active Three-Way Builds
Updated: Oct 6
The Alpine DP2-35M is a standalone 3.5-inch midrange from Alpine's second-generation DP-Series, rated at 50 W RMS (240 W peak) with a 90 Hz to 12 kHz response and 81 dB sensitivity. It uses the DP2 family's woven carbon-fibre hybrid cone and H.A.M.R. surround on a cast aluminium frame, and needs a 75.7 mm cutout. With an India MRP of ₹17,999, it is the midrange-only member of a range that also includes the DP2-65C two-way and DP2-653 three-way sets. It suits buyers adding a dedicated midrange to a DSP-driven system, or filling a factory midrange position in a car that has one. The current price is on our Alpine DP2-35M product page.
Quick summary
A 3.5-inch midrange only, with no crossover listed, so it must be band-passed by a DSP or a suitable network.
Alpine lists 81 dB sensitivity against 90 dB for the DP2 sets (test conditions unstated), so expect to level-match it in a processor.
Small enough for A-pillar pods and dash corners: 75.7 mm cutout, 34.2 mm depth and a 94.7 mm outer diameter.
We found no owner reviews of this exact model yet, so buy it for a planned build, not on reputation.

Dimensions, impedance and mounting come from Alpine Australia's DP2-35M page; sensitivity comes from Alpine Asia, which lists a ferrite magnet where the Australian page describes an ultra-high-density radial ring magnet. Neither page lists recommended crossover points.
What a standalone midrange is for
Most buyers never need a separate midrange, because a two-way set asks its 6.5-inch woofer to cover vocals as well as bass. The trouble is that a woofer in the door sits low and plays the vocal band off-axis, so singers seem to come from your knees. A midrange mounted high, on the A-pillar or in the dash, lifts that band to ear level and lets the woofer stick to what it does well.
Alpine itself pitches the DP2-35M at custom high-end builds, multi-speaker layouts and late-model cars with comprehensive factory speaker systems. In practice, that points to three jobs. The first is turning an existing two-way front stage into a three-way under DSP control. The second is replacing a factory dash or upper-door midrange in a car whose original system already has one. The third is a centre dash speaker, if your processor has a spare channel for it.
Note what it is not: a drop-in for a full-range factory speaker. Alpine lists no crossover with it, so it has to be told where to start and stop.
Crossovers, power and that 81 dB figure
A 3.5-inch cone cannot handle real bass, and feeding it full-range signal at any volume invites damage. The cleanest way to run the DP2-35M is from its own amplifier channel with a processor setting a band-pass. Alpine doesn't publish recommended crossover points for it, but there is a useful reference: Alpine's DP2-653NW network gives the midrange in the DP2-653 three-way set the band from 1.4 to 6 kHz. Alpine Australia lists that set's midrange with the same 75.7 mm cutout, 34.2 mm depth and 405 g weight as the DP2-35M. With a DSP you can start there and adjust by measurement for your car.
The 81 dB sensitivity matters for system design. Alpine quotes 90 dB for the DP2-65C and DP2-653 sets, without stating test conditions for either figure, so treat the gap as approximate. On those figures, the DP2-35M would play quieter than its partners for the same input, which a processor corrects with channel gain. That is another reason we'd run it active rather than as a passive add-on.
Power is not a concern at the 50 W RMS rating. The Alpine PXE-R80-8 offers eight 35 W RMS channels, enough for a fully active three-way front stage with two channels left over. Our step-by-step article on setting up a DSP in your car covers the tuning side.
What owners and reviewers say about the Alpine DP2-35M
When we checked in October 2026, we found no owner reviews, forum reports or independent tests of the DP2-35M. Alpine's own pages in Asia, India and Australia carry specifications and promotional copy but no customer feedback.
The nearest owner feedback we found is a 2023 Tesla Motors Club thread about a kit built around the first-generation DP-653 three-way set, not this midrange. Its owner reported a crisper, clearer sound than the factory speakers on the stock amplifier, and one reply pointed out that the factory speakers' neodymium magnets are more energy-dense than the Alpines' ferrite. It says nothing specific about the midrange, so read it only as background on the DP family.
Alpine's next-generation DP-Series page lists the DP2-35M in the range and credits the series with a redesigned motor structure; that is promotional material. If you have fitted a DP2-35M, we'd like to hear how it worked in your car.
DP2-35M, DP2-653 or another midrange?
If you are starting from scratch, the Alpine DP2-653 three-way set (₹48,999 MRP) already comes with 3.5-inch midranges alongside its woofers and tweeters. Buying a separate midrange makes most sense when you already own woofers and tweeters you want to keep. One example is the DP2-65C two-way set (₹43,999 MRP), from the same family, upgraded to three-way later under DSP control. Alpine doesn't list a passive network for that combination, so plan on active processing.
If you're weighing brands, our ESB 3.5-inch midrange review covers another driver aimed at custom three-way builds. Compare cutout and depth against your pod or factory opening before anything else.
Who should buy it, and who shouldn't
Buy the DP2-35M if you run, or are about to run, a DSP amplifier with two spare channels; you have woofers and tweeters you are happy with; and you can mount a midrange high in the car, in pods or a factory position.
Skip it if you want a simple speaker swap on head-unit power, or you have no way to band-pass it. In that case a complete set such as the DP2-653 or DP2-65C is the better buy.
Installation notes for Indian cars
The DP2-35M needs a 75.7 mm hole and 34.2 mm of depth, and the frame spans 94.7 mm, so check the outer diameter as well as the cutout before cutting a pod or a dash grille. Many installers give a pod midrange a small sealed space behind it, which keeps the rear wave from cancelling the front. Our article on aluminium pods for three-way systems shows how they are built.
Dash tops in an Indian summer get hot under the windscreen, so keep pods out of direct sun where you can, and seal them against dust. Aim the midranges towards the opposite seat for a wider stage, then let the processor's time alignment do the rest. VA3 Car Studio in Ghaziabad offers professional installation, so ask us to check your car before you order.
Price and where to buy
The DP2-35M has an MRP of ₹17,999. Alpine's pages that we read don't state whether it is sold singly or in pairs, so ask us to confirm the quantity before you order. We often sell below MRP; see the current offer on the DP2-35M listing. Every unit we sell is a genuine Alpine product.
The bottom line
The DP2-35M is a specialist part. In an active system with a processor, it gives an existing two-way stage a proper midrange from the same DP2 family, in a size that suits pods and dash positions. Without a DSP, the lack of a listed crossover and its modest 81 dB sensitivity make it hard to use well. Start from your plan: if you need a complete front stage, the DP2-653 set is simpler.
Alpine DP2-35M FAQ
Does the Alpine DP2-35M need a crossover?
Yes. It is a midrange only, rated from 90 Hz to 12 kHz, and it should never receive full-range signal. The cleanest approach is its own amplifier channel with a DSP band-pass, set by measurement in your car.
Can I add the DP2-35M to a DP2-65C two-way set?
Yes, with active processing. You need two more amplifier channels, one per midrange, and a DSP to set crossovers between the woofer, midrange and tweeter. Alpine doesn't list a passive network for that combination.
What crossover points suit the Alpine DP2-35M?
Alpine doesn't publish recommended points. For reference, its DP2-653NW network gives the three-way set's midrange 1.4 to 6 kHz, and Alpine lists the same cutout, depth and weight for that midrange. Tune from there by measurement.
